Answer:
The muscular work completed by four men will be 2400 ft. lbs.
Step-by-step explanation:
See the diagram of the ramp.
Four men carry 20 boxes each up a ramp as shown.
So, 4 men carry total (4 × 20) = 80 boxes up the ramp and each box weighs 5 pounds.
Then, the 4 men carry total (80 × 5) = 400 lb weight up the ramp.
Now, the vertical height of the ramp from the ground level is 6 ft.
Hence, the muscular work completed by four men will be (400 × 6) = 2400 ft. lbs. (Answer)
Answer:
Value of theta Ф = 1.33 radians
Step-by-step explanation:
We are given :
S= 8
r = 6
We need to find angle Ф
The formula used is: S=rФ
Finding theta Ф by putting values in formula:
So, value of theta Ф = 1.33 radians
22.5/5 = 4.5
For every 4.5 minute, she runs 5 km
Hope I wrote this clearly
This equation is in point-slope form. To change it to standard form, you must distribute -1/2 to (x+4) to get -1/2x-2. Your equation should now be y-8 = -1/2x-2. You should then add 1/2x to both sides (to cancel out -1/2x on the right side). Now, you should have y+1/2x-8 = -2. Finally, add 8 to both sides (to cancel out -8 on the left side) and flip the x and the y to get a final answer of 1/2x+y = 6.
